April 2007

Brief

Melampsora euphorbiae (Schub.) Cast. is reported from all continents but Antarctica. The rust fungus is living on a great number of Euphorbia species. In Norway it is found on five Euphorbia species (wild growing or cultivated outdoors), including the common weed sun spurge. To our knowledge M. euphorbiae on poinsettia has previously been reported only three times, namely in India, Tanzania, and Mauritius.
